A ping in both direction will help too. A traceroute to another IP in 66.140.63/24 network may help. To another IP in 66.140/16. To another IP in 66/8. Traceroute from and to the webmail machine could help too, find the difference, understand why there is difference and then you have your problem located. Then install wireshark (/usr/ports/net/wireshark-lite/) on the server from the ports and see what it says when you are trying to browse the server? Can you see the SYN packet? Does the server send the SYN/ACK packet? Install wireshark on your Mac client and do the same test, does yourclient send the SYN packet? Do you see the SYN/ACK sent bythe server? Desactivate the firewall on both machines. Olivier
